6 Claims.

This invention relates to improvements in air duct registers.

In warm air heating, Ventilating and air conditioning systems, a room ofthe building has the open end portion of a pipe or stack enteringthereinto. It is the practice to apply to the end of the stack or pipe aregister which is mounted against the wall into which the pipe or stackextends.

Heretofore, in most register constructions and installations it has beenvery difficult, if not impossible, to effect a gas tight connectionbetween the register and the end of the stack which will preventleakages around the register with resultant streaking and discolorationof the wall.

The Jones and Wagner co-pending application Serial No. 667,314, ledApril 22, 1933, discloses a construction which overcomes the aboveobjection by providing an arrangement which will effect a gas tightkseal between the register and the end of the stack. While thisconstruction has been very efficient and practical in use, it has beenfound that installations of said construction give some diiculty tounskilled workmen.

It is, therefore, the primary object of the present invention to providean air duct register construction wherein the end of the pipe or duct isconnected with the register in such a manner that a Vgas tight seal willbe effected whichV will prevent leakage around the register, theconstruction, moreover, being simple and susceptible of easyinstallation with a minimum amount of time and effort. l

A further object of the invention is to provide an air duct registerwherein the parts thereof, including the register face or grille,are'readily lseparable and removable, and. which, when in place, issecurely held against undesired disengagement.

A further object of the invention is to provide an air duct registerwherein the register face' or grille will lie flatly against the surfaceof the wall and wherein there will be no exposure of the periphery ofthe wall opening into which the stack extends, due to shrinkage asbetween the register face and wall.

A further object of the invention is to provide a register construction,which, irrespective of its length or size, is readily attachable tostudding having standard spacing.

A further object of the invention is to provide an air duct registerwhich is ci very simple construction, is inexpensive and easy tomanufacture and install, is neat and attractive in appearance, and iswell adapted for the purposes set forth.

With the above and other objects in view the invention consists of theimproved air duct register, and its parts and combinations as set forthin the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference charactersindicate the same parts in all of the views:

Fig. 1 is a iront view of the improved air duct register shown mountedon studding, a portion of the grille being broken away to showconstructional details;

Fig. 2 is a longitudinal sectional view taken on line 2 2 of Fig. 1 andshowing the application of laths and plaster over the attaching flanges;

Fig. 3 is a fragmentary detail sectional view taken on line 3--3 of Fig.l and on a larger scale;

Fig. 4 is a fragmentary detail sectional View taken on line 4 4 oi Fig.1 and on a larger scale; and

Fig. 5 is an enlarged fragmentary detail sectional view illustrating amodication of the invention.

Referring now more particularly to the drawing, it will appear that theregister is adapted for installation in a wall having an openingStherein 7 between studding members 9 which have the usual spacingarrangement of sixteen inches between centers. The outer end portion ofa pipe or stack 10 extends into said opening 8 and said pipe end portionis adapted to have the improved register construction applied thereto.To adapt the end portion of the pipe or stack for connection with theimproved register it is necessary that the four corner portions of thepipe be slit inwardly a substantial distance, the said slits beingindicated by the numerals 11 in the drawing. The portions of the pipeend separated from one another by said slits are bent outwardly atslight angles to the planes of the pipe walls thereadjoining, formingyielding sheet portions 12.

To provide a means of mounting the register and to frame the opening 8,a rectangular metallic frame indicated generally by the numeral 13 isprovided. Said frame is formed with end flanges 14 and side ilanges 15,all at and in the same plane. Adjoining the' inner edges of said iianges14 and 15 the metal is bent outwardly at right angles to said flanges asat 17, and then outer face ribs 16 are formed by the metal being bent atright angles to the portions 17. Bent inwardly from the inner edges ofthe ribs 16 are inwardly angled stack engaging iianges 18.

Ordinarily the studding members 9 are sixteen inches between centers andirrespective of thev size of the central opening in the frame 13, the

anges 14 are sufficiently long to engage adjacent studding members 9,and the fra-rneis secured thereto by nails or screws 19 driven throughsaid flanges and into the studding. If an extremely long register isdesired an elongated frame may be provided which will span anintermediate studding member and be attached to studding members on,thirty-two inch centers.

The register face or grille 20 is a rectangular metallic sheet, and,save for a substantial margin, is formed with alternate openings andbars, or is of lattice-work or other ornamental, open-work design,whereby air may freely ow therethrough. Welded or otherwise secured to`the inner `face of the marginal portion of the grille, substantiallyinwardly of the edge portion thereof, is la sealing and grille locatingframe 21. Legs 22 o f said sealing frame are biased inwardly slightlyfrom perpendicular to the inner face of the grille :and said legs areformed of yieldable metal. The free end portions Aof said legs areformed with inwardIy turned guiding rolled portions 2.3-

When lthe improved yregister is to ,be assembled and installed `theinner end portion of the pipe or stack 1,0 is first provided with thecorne-r slits ll, as previously described. The metallic frame 13 is nextpositioned in the wall opening 8 and is secured rto faces Aof the spacedstudding members 9. rIhe yielding sheet portions 12 of the staCk, .denedby the slits 11 are positioned adjacent and bent toward face portions ofthe Iflanges 18 `of the frame 13,. The next step is the positioning andattaching or" the register face or grille 2 0. The grille is ycorrectlylocated by the legs 22 which venter the frame opening and Said legs,being inwardly inclined, slide along the stack portions 12 and when thegrille is in position `said legs yieldine'ly impinse against Said stackportions and securely clamp said stack portions aga-inst the frameflanges A18. In this way a gas-tight seal is eiected between the innerend portion of the stack and the register frame. The register face orgrille is removably held in position by means oi screws 24 passedthrough corner openings in the grille and into portions vof the .ribs1,6 of the frame. With the grille resting against the frame ribs 16,said face is removed laterally outwardly from the faces of the studding9. Lathing 25, and plaster 26 is builtl up outwardly of the flanges 14to the plane of the ribs 1,6 `to complete the room wall around theopen-l ing 8.

In the modified form of air duct register 4disclosed in Fig. 5 the stack1,0 is formed in the manner previously described with slits 1-1 dennilgyielding, outwardly bent sheet portions 12. The frame 13 is formed witha rectangular outwardly projecting collar surrounding the openingthrough the frame. Said collar is formed by portions 17 fiangedoutwardly from the inner margins of the end iianges 14 and the sideiianges, said portions 17 being at acute angles to said end and sideflanges. Projecting outwardly from the ends of the portions 17 in planesparallel ,to the planes of the end and side iianges, are grille engagingflanges 16. The inner face of the register face or grille 20, inwardlyof its outer margin, carries an inwardly projecting frame havinginwardly inclined legs 22'.` The register grille is positioned so as torest on the flanges 16 and is secured thereto by screws 24, while thelegs 22 impinge against the stack portions 12 and clamp the same againstthe inner frame portions 17 to provide a seal between the stack endportion and the register frame.

.sembly rthe grille can be removed whenever desired for repairs orcleaning operations.

From the' .foregoing description it will be seen 1that the improved airduct register is both simp le and novel, and is well adapted for thepurposes described.
